Table 9 Possible Problems
Possible Problem Suggested Solutions
My telephone has no dial tone. The display
panel is blank.
■
Verify that the power cord is fully inserted in the correct connector
on the underside of the telephone. Use the strain relief tab to
prevent the cord from becoming unplugged.
■
Verify that each RJ45 cable is connected and that each cable is in
the proper connection.
■
Remove and add power to the telephone by unplugging the power
cord at the electric outlet and plugging it back in.
■
If the telephone is powered through a powered RJ45 cable, make
sure that power is applied to the cable at its source.
My telephone has “locked up.”
■
Your telephone has lost the connection to the system. Remove the
RJ45 cable from the jack, and then re-insert it into the jack.
■
Wait a few seconds. If the telephone still appears to be locked,
disconnect the electrical power for your telephone, and then plug it
back in.
Callers cannot leave messages on my voice
mail.
■
Your mailbox may be full. Log in to your voice mailbox and delete
some messages.
■
Your telephone may be set up for Greeting Only Mailbox. Log in to
the NBX NetSet utility and go to
NBX Voice Mail Settings >
Personal Greeting and clear the Greeting Only Mailbox
checkbox.
When I park a call, the display panel shows
Park xtn in use
, and the call returns to
my telephone.
You have selected a Call Park extension that is already in use. Try
another Call Park extension. Your administrator can add additional
Call Park Extensions. For details, see
“Call Park” in Chapter 7 .
When I dial 9 or 8 to access an outside line,
the display panel shows
All Ports
Busy
.
No outside lines are available. Try again in a few minutes.
After I call another user in my organization,
I hear a tone but no ringing.
The other user may have the Hands Free Active on Intercom feature
enabled. Begin speaking after you hear the tone.
When I try to access the NBX NetSet
™
utility, I do not get a response after I type
the NBX system’s IP address and press
Enter .
Ask your administrator to verify the IP address that you typed into your
web browser.
I am unable to log in to the NBX NetSet

You must set up your voice mail before you can use the NBX NetSet
utility. Press the Message button. The prompts guide you through the
setup. Then use your voice mail password to access the NBX NetSet
